The connection to the power supply must be via a 5-wire line. For safety reasons, the PE protective
conductor must always be connected.
The power supply line must be equipped with an appropriate line protection. More information regarding the
power connection you will find in the Technical Data, page 61.
Always observe the following standards:
IEC 60364-4-41
Protective measures: protection against electric shock
IEC 60364-4-43
Protection for safety: protection against overcurrent
IEC 60364-5-52

The respectively national standards are to be upheld.
The following specifications of the local grid operator are to be observed:
•
Pertinent technical and special regulations
•
Installation approval must be in place
•
Check the line voltage. It must be within the technical data for that device. If the line voltage is
higher, contact your local network operator.
•
The AC side must not be measured by inserting test probes into the AC plug, because this will
damage the plug contacts.
Note:
To ensure the IP65 protection class, only use the male and female
connectors provided and connect them according to the connector
manufacturer's mounting instructions. To prevent any penetration of
moisture and dirt, unused inputs and outputs must be properly closed.
Failure to do so could void your warranty!
Note:
When using wire end ferrules with isolating collar, make sure you do not
introduce the insulation of the wire end ferrule into the clamping area of the
terminal.
